Unfortunately checking ownership means comparing jobjects, which you can't safely do if you are comparing to a jobject that could be freed at any moment (I'm referring the JNI ref being freed, not the object being GC'd). I ran into asserts in JNI IsSameObject() due to this happening. Basically the local ref became invalid between the time it was fetched from the DebugRawMonitor and when is was used by IsSameObject(). ------------- PR Comment: https://git.openjdk.org/jdk/pull/19044#issuecomment-2119592870
